I've been preparing to add about 4 hens to my flock but I'm concerned that with the extreme heat forecast for this week (107 today!) all the girls might become stressed out. Is this something I should be concerned about? The new hens will be in quarantine in the corner of my barn- out of the sun- but it's still about 102 in there at the peak of the day. My other hens free range all day and often hang out in the barn stay cool. They'll likely see the new arrivals. Any thoughts?
